It is difficult to sell an idea when it is just an idea or a concept.
However if one takes further steps to convert those ideas into intangible property then it is quite possible to monetise your idea.
In law, there is no property right given over a concept or an idea.
One cannot claim ownership rights over an idea as ideas are subject to public domain.
Is it possible to make money out of your ideas? I have encountered some people who are naturally gifted with a creative mind.

Is it therefore possible to make money out of ideas perhaps by selling the ideas or exchanging them? It is difficult to sell an idea when it is just an idea or a concept.
